Wavelength division multiplexing with four transceivers
Here, we develop a novel design approach that co-optimizes inverse-designed wavelength division multiplexers and distributed Bragg gratings to achieve ultra-low crosstalk without compromising insertion loss. Current solutions are limited by trade-offs between channel spacing, crosstalk, insertion. In the relentless pursuit of higher bandwidth and more efficient fiber utilization, wavelength division multiplexing (WDM) technologies are fundamental. But navigating the alphabet soup of CWDM, DWDM, MWDM, LWDM, and SWDM can be daunting.
